FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view of the right side thereof, the opposite side being identical; and,

FIG. 4 is an enlarged fragmentary front elevational view thereof.

The broken line showing of the tire sidewall in the drawing is for illustrative purposes only and forms no part of the claimed design. The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 2.
